Audiobus: Your virtual music studio.
What is Audiobus? — Audiobus is an award-winning music app for iPhone and iPad which lets you use your other music apps together. Chain effects on your favourite synth, run the output of apps or Audio Units into an app like GarageBand or Loopy, or select a different audio interface output for each app. Route MIDI between apps — drive a synth from a MIDI sequencer, or add an arpeggiator to your MIDI keyboard — or sync with your external MIDI gear. And control your entire setup from a MIDI controller.Download on the App Store
Audiobus is the app that makes the rest of your setup better.
How do you make DnB beats on ios?
Here's one way using DM1 and SunVox. If you don't have SunVox I highly recommend it, probably worth it's small price just for this one effect. I use special effect 7 and by interpolating the start of the loop to the end, each step is given a number and the beat is effectively chopped into 32 equal parts (a bit like a REX file). I can then copy/paste, move parts and generally rearrange and mangle the beat..
